PitchRight allows you to correct the pitch of vocals or any instrument in real time. 3 parameters control operation: 'Ratio" sets the amount of pitch correction, 'Smoothing" sets the correction for vibrato, and 'Calibrate" sets the reference pitch. Unlike other pitch correction programs, smoothing does not influence the transition between notes. 13 factory preset scales, 2 user scales, and MIDI scales are available. With the MIDI function you can control pitch from an external MIDI keyboard via a MIDI sequencer.
